DOB produces 69 documented subjective effects across 7 categories.
Full DOB profileThe first indication that DOB has taken hold arrives slowly, almost teasingly. An hour passes after ingestion, then two, and the only clues are a subtle electrical hum in the muscles and a faint metallic taste at the back of the throat. By the third hour, a creeping stimulation has settled into the body, unmistakable and insistent. The heart beats harder and faster than usual. The jaw tightens with a determined clench. There is a building pressure behind the eyes, as if the brain itself were swelling to accommodate something vast. The amphetamine backbone of DOB makes itself known through a driven, restless energy that anchors the entire experience in the body.
As the come-up continues to unfurl, the visual field begins to transform. Colors intensify with an almost aggressive vividness, as though someone has turned the saturation dial far past its natural limit. Geometric patterns emerge not as gentle overlays but as commanding, angular structures. They tile across surfaces with a mechanical precision, intricate and relentless, pulsing in time with the user's heartbeat. There is a sharpness to DOB's visuals that distinguishes them from softer psychedelics. Everything feels etched, heightened, almost too real. Walls, ceilings, and floors may appear to ripple with crystalline grids of impossible intricacy.
At the peak, which can stretch across four to six hours beginning around hour three or four, the stimulation and psychedelia fuse into an experience of sustained intensity. The mind races with ideas that feel both lucid and grandiose. Conversations may take on an exhausting momentum, careening through topics with manic energy. Emotionally, there is a volatility that mirrors the physical drive: euphoria, awe, irritability, and paranoia can all surface within the same hour. Body temperature regulation becomes unreliable, and fluctuations between sweating and chills are common. The pupils are widely dilated, and peripheral vasoconstriction may cause the fingers and toes to feel cold or tingling, even as the core runs hot.
The descent from DOB is one of its most defining and, for many, most punishing features. The experience does not simply end after six or eight hours. Instead, it tapers with agonizing slowness across another six to twelve hours, sometimes longer. The stimulation persists long after the psychedelic intensity has faded, leaving a wired, hollowed-out restlessness that resists sleep. The jaw remains sore. The body feels like a machine that has been running at redline for too long. When sleep finally comes, it arrives heavy and dreamless, and the following day is often marked by a dull, depleted fatigue that lingers into the evening.
Abnormal heartbeat (arrhythmia) is any deviation from the heart's normal rhythm — including beats that are too fast (tachycardia), too slow (bradycardia), or irregularly spaced — and represents one of the more medically significant cardiovascular effects of psychoactive substances.
Appetite suppressionA distinct decrease in hunger and desire to eat, ranging from reduced interest in food to complete disinterest or even physical revulsion at the thought of eating. This effect can persist for many hours beyond the primary experience.
Bodily control enhancementBodily control enhancement is the subjective feeling of improved physical precision, coordination, and dexterity — a sense of heightened mastery over one's own body that can make movements feel fluid, deliberate, and effortless.
Changes in felt bodily formChanges in felt bodily form is the experience of one's body feeling as though it has altered its physical shape, structure, or organization — such as stretching, folding, splitting, or gaining extra limbs — in ways that are felt rather than seen.
DehydrationA state of insufficient bodily hydration manifesting as persistent thirst, dry mouth, and physical discomfort, often caused by increased sweating, urination, or simply forgetting to drink water during substance use.
DiarrheaDiarrhea is the occurrence of frequent, loose, or watery bowel movements as a side effect of certain psychoactive substances, resulting from either direct GI irritation or pharmacological alterations to gut motility and fluid absorption.
Difficulty urinatingDifficulty urinating, also known as urinary retention, is the experience of being unable to easily pass urine despite a full bladder, commonly caused by stimulant, opioid, and anticholinergic substances that affect bladder muscle control.
Increased blood pressureIncreased blood pressure (hypertension) is an elevation of arterial pressure above the normal 120/80 mmHg baseline, commonly caused by stimulants, vasoconstrictors, and substances that activate the sympathetic nervous system, posing cardiovascular risks that increase with dose and pre-existing conditions.
Increased heart rateA noticeable acceleration of heartbeat that can range from a subtle awareness of one's pulse to a forceful, rapid pounding felt throughout the chest, neck, and temples. This effect is among the most commonly reported physiological responses to psychoactive substances and often accompanies stimulation, anxiety, or physical exertion during intoxication.
Increased salivationIncreased salivation (hypersalivation or sialorrhea) is the excessive production of saliva beyond what can be comfortably swallowed, commonly occurring with psychedelic tryptamines and certain antipsychotics as part of a broader parasympathetic activation pattern.
Muscle crampMuscle cramps are sudden, involuntary, and often painful contractions of muscles that occur as a side effect of certain psychoactive substances, particularly stimulating psychedelics and stimulants.
NauseaAn uncomfortable sensation of queasiness and stomach discomfort that may or may not lead to vomiting, often occurring during the onset phase of many substances.
Physical euphoriaAn intensely pleasurable bodily sensation that can manifest as waves of warmth, tingling electricity, or a full-body orgasmic glow radiating outward from the core. This effect is often described as one of the most rewarding physical sensations available through psychoactive substances and is a primary driver of the recreational appeal of many substance classes.
Pupil dilationA visible enlargement of the pupil diameter (mydriasis) that can range from subtle widening to dramatic saucer-like expansion where the dark pupil dominates the iris. This effect is one of the most recognizable signs of psychedelic and stimulant intoxication and directly contributes to light sensitivity, enhanced color perception, and the characteristic "wide-eyed" appearance.
Restless legsRestless legs is an uncomfortable neurological effect characterized by an irresistible compulsion to move the legs (and sometimes other limbs) to relieve unpleasant crawling, aching, or tingling sensations, particularly during periods of rest or inactivity.
SedationA state of deep physical and mental calming that manifests as a progressive desire to remain still, lie down, and eventually drift toward sleep. Sedation ranges from a gentle drowsy relaxation to a heavy, irresistible pull into unconsciousness where maintaining wakefulness becomes a losing battle against the body's insistence on shutdown.
Stamina enhancementStamina enhancement is an increase in one's ability to sustain physical and mental exertion over extended periods without succumbing to fatigue, achieved through substances that modulate energy metabolism, pain perception, or central fatigue signaling.
StimulationA state of heightened physical and mental energy characterized by increased wakefulness, elevated motivation, and a subjective sense of vigor that pervades both body and mind. Users often report feeling electrically alive, with a buzzing readiness to move, talk, and engage that can range from a pleasant caffeine-like lift to an overwhelming, jittery compulsion to act.
Stomach crampStomach cramps are sharp, intermittent pains in the abdominal region that can occur when psychoactive substances irritate the gastrointestinal lining or alter the normal patterns of smooth muscle contraction in the digestive tract.
Teeth grindingAn involuntary clenching and rhythmic grinding of the jaw muscles, known clinically as bruxism, that produces a compulsive need to clench, chew, or gnash the teeth together. This effect can range from a subtle tightness in the jaw to forceful, repetitive grinding that can cause significant dental damage and jaw pain during and after the experience.
Temperature regulation disruptionImpaired thermoregulation causing unpredictable fluctuations between feeling hot and cold, with risk of hyperthermia or hypothermia.
VasoconstrictionA narrowing of blood vessels throughout the body that produces sensations of cold extremities, tingling in the fingers and toes, and a general feeling of circulatory restriction. Users may notice their hands and feet becoming pale, numb, or uncomfortably cold, sometimes accompanied by a sense of tightness in the chest or head.
A visual phenomenon in which a faint, ghostly imprint of a previously viewed image persists in the visual field after the original stimulus has been removed or one has looked away. These lingering visual echoes are significantly more persistent, vivid, and detailed than normal physiological afterimages, often retaining color and form for several seconds or longer and overlaying themselves onto whatever one currently views.
Brightness alterationPerceived increase or decrease in environmental brightness beyond actual illumination levels, common with stimulants and psychedelics (brightening) or sedatives (darkening).
Colour enhancementAn intensification of the brightness, vividness, and saturation of colors in the external environment, making the world appear dramatically more colorful. Reds seem redder, greens seem greener, and all hues appear richer and more distinct than during ordinary perception.
Colour shiftingThe visual experience of colors on objects and surfaces cycling through continuous, fluid transformations, shifting from one hue to another in smooth, seamless loops. A green surface might flow through blue, purple, red, and back to green in a mesmerizing animated sequence.
Depth perception distortionsAlterations in how the distance of objects within the visual field is perceived, causing layers of scenery to appear exaggerated, rearranged, flattened, or warped in spatial depth.
DiffractionThe experience of seeing rainbow-like spectrums of color and prismatic halos embedded within bright light sources and reflective surfaces, caused by pupil dilation altering how light enters the eye.
DriftingThe visual experience of perceiving stationary objects, textures, and surfaces as appearing to flow, breathe, melt, or shift in position. Drifting is one of the most fundamental and commonly reported visual distortions under the influence of psychedelic substances, serving as the perceptual foundation upon which many other visual effects are built. It manifests as a fluid, organic sense of motion embedded in otherwise static visual fields.
External hallucinationA visual hallucination that manifests within the external environment as though it were physically real, ranging from subtle distortions of existing objects to fully autonomous, detailed scenes and entities that appear indistinguishable from reality.
GeometryThe experience of perceiving complex, ever-shifting geometric patterns superimposed over the visual field or visible behind closed eyelids. Geometry is widely considered the hallmark visual effect of psychedelic substances, ranging from simple lattice patterns and honeycombs at low doses to infinitely complex, self-transforming fractal structures at high doses that can feel profoundly meaningful and awe-inspiring.
Internal hallucinationVivid, detailed visual experiences perceived within an imagined mental landscape that can only be seen with closed eyes, ranging from fleeting imagery and abstract scenes to fully immersive, dream-like environments with autonomous narratives and entities.
Pattern recognition enhancementAn increased ability and tendency to perceive meaningful patterns, faces, and images within ambiguous or random visual stimuli such as textures, clouds, and surfaces.
Perspective distortionsDistortion of perceived depth, distance, and size of real objects, making things appear closer, further, larger, or smaller than they actually are.
Perspective hallucinationA hallucinatory phenomenon in which the observer's visual perspective shifts from the normal first-person viewpoint to alternative vantage points — including third-person (seeing oneself from outside), bird's-eye, or omniscient perspectives — during both internal and external hallucinations.
Settings, sceneries, and landscapesThe perceived environment in which hallucinatory experiences take place, ranging from recognizable locations drawn from memory to entirely novel alien landscapes, ancient civilizations, cosmic vistas, and impossible architectural spaces.
Shadow peopleThe perception of dark, humanoid silhouettes lurking in peripheral vision or standing in direct line of sight, appearing to move and behave as autonomous, sentient beings. These entities feel disturbingly real and are a hallmark of deliriant intoxication and sleep deprivation.
Symmetrical texture repetitionTextures appear to mirror and tessellate across surfaces in intricate, self-similar symmetrical patterns that maintain detail at every scale. Most prominent in peripheral vision on rough surfaces.
TracersMoving objects leave visible trails of varying length and opacity behind them, similar to long-exposure photography. Trails may match the object color or appear in other hues.
TransformationsObjects and scenery undergo perceived visual metamorphosis, smoothly shapeshifting into other recognizable forms over seconds. Patterns morph into faces, animals, and imagery.
Visual acuity enhancementVision becomes sharper and more defined than normal, as though a slightly blurry lens has been brought into perfect focus. Edges appear crisp and fine details become vivid.
A perceived improvement in one's ability to logically deconstruct concepts, recognize patterns, and reach novel conclusions, often accompanied by deep states of contemplation and an abundance of insightful ideas.
Analysis suppressionAnalysis suppression is a cognitive impairment in which the capacity for logical reasoning, critical evaluation, and systematic problem-solving is significantly diminished — leaving the person unable to effectively break down, examine, or draw conclusions about even relatively simple ideas or situations.
AnxietyIntense feelings of apprehension, worry, and dread that can range from a subtle background unease to overwhelming panic attacks with a sense of impending doom, often amplified by the substance's intensification of one's existing mental state.
Cognitive euphoriaA cognitive and emotional state of intense well-being, elation, happiness, and joy that manifests as a profound mental contentment and positive outlook. This ranges from gentle feelings of optimism and warmth to overwhelming bliss that pervades all thoughts and perceptions.
Conceptual thinkingA shift in the nature of thought from verbal, linear sentence structures to intuitive, non-linguistic concepts that are felt and understood rather than spoken by an internal narrator.
ConfusionAn impairment of abstract thinking marked by a persistent inability to grasp or comprehend concepts and situations that would normally be perfectly understandable during sobriety.
Immersion enhancementA heightened capacity to become fully absorbed and engrossed in external media such as music, films, video games, and art, with an amplified suspension of disbelief and a deepened emotional connection to the content being experienced.
Increased sense of humorA general amplification of one's sensitivity to finding things humorous and amusing, often causing previously unremarkable stimuli to become inexplicably hilarious, with laughter triggered by observations and connections that seem profound or absurd in the altered state.
IrritabilityIrritability is a sustained state of emotional reactivity in which the threshold for annoyance, frustration, and anger is significantly lowered — causing minor inconveniences, social interactions, or environmental stimuli that would normally be tolerated without difficulty to provoke disproportionate agitation or hostility.
Language suppressionA diminished ability to formulate, comprehend, or articulate language, ranging from difficulty finding the right words to a near-complete inability to construct coherent sentences or understand speech, despite remaining otherwise conscious.
Memory suppressionA dose-dependent inhibition of one's ability to access and utilize short-term and long-term memory, ranging from mild forgetfulness to a profound inability to recall personal identity, biographical information, or the context of the current experience.
Novelty enhancementA feeling of increased fascination, awe, and childlike wonder attributed to everyday concepts, objects, and experiences, as if perceiving the world for the first time.
ParanoiaIrrational suspicion and belief that others are watching, plotting against, or intending harm toward oneself, ranging from mild unease to overwhelming terror.
PsychosisPsychosis is a serious psychiatric state involving a fundamental break from consensus reality — characterized by firmly held false beliefs (delusions), perception of things that are not there (hallucinations), disorganized thought and speech, and a loss of the ability to distinguish internal mental events from external reality.
Sensed presenceSensed presence is the vivid and often unshakeable feeling that an unseen conscious being — whether benevolent, malevolent, neutral, or inscrutable — is present nearby or within one's own mind, despite the complete absence of any visual, auditory, or tactile confirmation.
Suggestibility enhancementHeightened receptivity to external suggestions, ideas, and influence, commonly experienced during psychedelic and hypnotic states.
Thought accelerationThe experience of thoughts occurring at a dramatically increased rate, as if the mind has been shifted into a higher gear. Ideas, associations, and internal dialogue cascade rapidly, often outpacing the ability to articulate or fully process each one, producing a subjective sense of heightened mental velocity.
Thought connectivityA state in which disparate thoughts, concepts, and ideas become fluidly and spontaneously interconnected, revealing patterns and relationships that are normally overlooked. The mind weaves together seemingly unrelated subjects into a unified web of associations, often producing novel insights or a profound sense of conceptual coherence.
Thought loopsBecoming trapped in a repeating cycle of thoughts, actions, and emotions that loops every few seconds to minutes. Short-term memory lapses cause the sequence to restart.
Time distortionSubjective perception of time becomes dramatically altered — minutes may feel like hours, or hours pass in moments. Can manifest as either dilation or compression.
WakefulnessAn increased ability to stay awake and alert without the desire to sleep. Distinct from stimulation in that it does not elevate energy above a naturally rested baseline.
Scenarios and plots are the narrative structures that emerge within hallucinatory states — coherent or surreal storylines involving autonomous characters, unfolding events, and immersive settings that can feel as real and consequential as waking life.
SynaesthesiaStimulation of one sense triggers involuntary experiences in another — seeing sounds as colors, tasting textures, or hearing visual patterns. A blending of sensory channels.
A profound dissolution of the sense of self in which personal identity, memories, and the boundary between self and world completely vanish, leaving only pure undifferentiated awareness.
Existential self-realizationA sudden, visceral realization of the profound significance and improbability of one's own existence as a conscious being within the universe, often accompanied by overwhelming awe and a fundamental shift in perspective about life and reality.
Unity and interconnectednessA profound sense that identity extends beyond the self to encompass other people, nature, or all of existence. Boundaries between self and other dissolve into felt oneness.
